I am trying to install Elasticsearch 2.2.0 and I am getting this errors: ./elasticsearch: line 75: dirname: command not found ./elasticsearch: line 98: dirname: command not found ./elasticsearch: line 125: uname: command not found ./elasticsearch: line 134: hostname: command not found ./elasticsearch: line 134: cut: command not found ./elasticsearch: line 138: egrep: command not found Error: Could not find or load main class org.elasticsearch.bootstrap.Elasticsearch I found that there was a similar topic and the problem was in the Java version. I have jdk1.8.0\_60.jdk, jdk1.8.0\_131.jdk and jdk1.6.0.jdk, so I checked my Java path in case it might be pointing on the 1.6 version but actually it is not: macs-MacBook-Pro-2:bin mac$ echo $JAVA\_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0\_131.jdk/Contents/Home I even removed the 1.6 version but I'm still getting the same error. Thank you in advance for your help. ---

What did you download exactly? Sounds like you are running on a Mac, right? Should be pretty much straightforward: - Download the tar.gz - tar xzf thefile - cd thedir - bin/elasticsearch Are you doing any other step you did not mention yet? ---

I am still getting errors: ``` Last login: Thu May 11 18:28:39 on console -bash: touch: command not found controller:~ mac$ cd /Users/mac/Documents controller:Documents mac$ tar xzf elasticsearch-5.4.0 -bash: tar: command not found controller:Documents mac$ cd /Users/mac/Documents/elasticsearch-5.4.0/bin controller:bin mac$ elasticsearch -bash: elasticsearch: command not found controller:bin mac$ ./elasticsearch ./elasticsearch: line 48: grep: command not found ./elasticsearch: line 108: dirname: command not found ./elasticsearch: line 142: dirname: command not found Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker Elasticsearch requires at least Java 8 but your Java version from /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java does not meet this requirement controller:bin mac$ ``` I downloaded it from [https://www.elastic.co/downloads/elasticsearch](https://www.elastic.co/downloads/elasticsearch) Even the "tar" command didn't work so I had to open the file using Archive Utility. I am thinking maybe there is something wrong in the ".bash\_profile" file. Can you please show me an example of how it looks like by default? ---

Probably you screwed up your path if you modified it. ---

I was pointing in my ES\_HOME path on another version of Elasticsearch that I don't have anymore. I have just modified the path.

It is working now. I reset my ".bash\_profile" file.
